Chaga extraction technology
Chaga extract is a modern high-tech product obtained by aqueous extraction of raw materials followed by freeze-drying.
Our Chaga Extraction Technology.
Chaga extract from VISTERRA is produced by vacuum freeze-drying. The technology preserves all active substances in the extract put there by the nature itself. It is this chaga extract that is valued more than others in all countries.
The most important indicator of the effectiveness and quality of chaga extract is the chromogenic complex. The use of innovative technologies in production allows us to obtain an extract with an increased content of the chromogenic complex - from 50 to 65%. The cost of chaga extract directly depends on the size of the chromogenic complex.
The second most important component of chaga extract is beta-glucan. According to the analysis results, its content in our chaga extract is 27.1%. Beta-glucan has immunomodulatory, antitumor and anti-inflammatory effects.
Extraction ratio – 12:1. It means that manufacture of 1 kg of the extract requires 12 kg of chaga mushroom.
The chaga processing technology includes a number of sequential operations - sorting of raw materials, washing, drying, grinding, water extraction, purification of the extract (separation), vacuum concentration of the extract, sterilization of the thick extract, freeze drying to obtain a dry extract, grinding the dry extract, quality control.
The most important process that determines the quality of the dry extract is the aqueous extraction of the fungus. The completeness of the extraction of biologically active substances from the fungus and their composition depend primarily on the temperature of the extractant. Some substances are extracted at temperatures below 60 ° C, but they are destroyed at a higher temperature; other components need an increase in temperature or less harsh extraction conditions. Visterra has developed a unique technology for deep extraction of chaga at temperatures below 60 ° C using mechanical, hydrodynamic and other factors for activating raw materials with the maximum extraction of a natural complex of biologically active substances. Two-stage purification of the extract using a decanter and a separator makes it possible to completely get rid of fragments of the chaga structure formed during grinding of the mushroom and the impact of mechanical and hydrodynamic loads during extraction.
Concentration of the extract is carried out in two stages. In vacuum evaporators up to a dry residue content of about 30% followed by removal of moisture in vacuum mash reactors to a dry matter content of about 45%, when the thermal conductivity is still sufficient to ensure the homogeneity of the thick extract and fluidity of the extract for discharge. Further removal of moisture from the thick extract to obtain a dry extract (chaga powder) is carried out by vacuum freeze drying. The freeze-dried chaga extract is a dark brown, almost black powder that is highly soluble in water.
